Investigation of Adenovirus and Rotavirus Frequencies and Seasonal Distribution in Patients with Gastroenteritis

Purpose: The aim of the study was to determine the incidence and seasonal distribution of rotavirus group A and enteric adenovirus serotypes 40 and 41 in all age groups admitted to our hospital with acute gastroenteritis. Materials and Methods: Results of the patients from all ages with the pre-diagnosis of acute gastroenteritis between January 2016 and December 2019 were retrospectively evaluated. A total of 10,049 patient results in which rotavirus antigen was investigated in stool samples and 11.482 patient results in which adenovirus antigen was investigated in stool samples were included in the study. Rotavirus and adenovirus positivities were investigated by using immunochromatographic method. Results: In the distribution of rotavirus and adenovirus antigen positivity according to years, the highest positivity for both viral agents was recorded in 2016 and in winter months. According to this result, rotavirus positivity rate was 18.4% and adenovirus positivity rate was 3.5% in 2016. While the frequency of rotavirus antigen positivity was the highest in the age group between 0-2 years the frequency of adenovirus antigen positivity was the highest in the age group between 3-5 years. Conclusion: The epidemiology of the disease must absolutely be followed up with surveillance studies within the scope of fight against viral gastroenteritis. Our study in which there are data of four years will contribute to establishing the country data.
